Abstract: A protective enclosure for an electronic device includes a top member adapted to be removably coupled to a bottom member to enclose the electronic device. A first back engagement feature is disposed on an inside surface of a perimeter wall portion of the bottom member, and the first back engagement feature is adapted to engage a first front engagement feature disposed on an inner perimeter wall of the top member to removably secure the top member to the bottom member. A second back engagement feature is disposed on an outside surface of the perimeter wall portion of the bottom member, and the second back engagement feature is adapted to engage a second front engagement feature disposed on an outer perimeter wall of the top member to further removably secure the top member to the bottom member.

Abstract: A mount assembly for releasably receiving a mounting cleat includes a top housing portion, a bottom housing portion, and a recess in the top housing portion to receive the mounting cleat. The mount assembly further includes a biasing device connected to housing portions such that the biasing device exerts a force upon the top housing portion which tends to return the top housing portion to an unrotated position relative to the bottom housing portion. The mount assembly further includes a first clasp mechanism and a second clasp mechanism at least partially disposed within the top housing portion extendable into the recess to clasp the mounting cleat when the top housing portion is in the unrotated position. Finally, the mount assembly includes a locking mechanism configured to temporarily prevent rotation of the top housing portion relative to the bottom housing portion when the locking mechanism is in a locked position.

Abstract: A system for detecting presence of a protective case on an electronic device includes a removable protective case for an electronic device and a set of computer instructions storable on a non-transitory storage medium. The set of computer instructions is executable by one or more computer processors of the electronic device to generate a vibration in the electronic device through activation of a haptic motor of the electronic device. The instructions are further configured to receive data measured by an accelerometer of the electronic device, where the data is measured during the generation of the vibration, and compare the received data to a known vibration signature of the electronic device to determine if the protective case is attached to the electronic device.

Abstract: A protective case for a portable electronic device is provided. The portable electronic device has a device connector for transmission of data and/or power between the device connector and a data and/or power source via a reciprocal connector assembly. The case includes an aperture disposed proximate the device connector of the installed portable electronic device, the aperture passing between an outer surface and an inner surface of the case and defined by a surface between the outer and inner surfaces, the aperture having a circumference; and a compliant seal surrounding the circumference of the aperture, the compliant seal to interface with at least a portion of the backshell portion of the reciprocal connector assembly to seal the aperture when the reciprocal connector assembly is inserted through the aperture to interface with the device connector of the installed portable electronic device.

Abstract: A mounting system with a lock switch can be used to releasably attach a first item, such as a protective encasement for an electronic device, to a second item, such as a bicycle mount, suction cup mount, or a surface in a home, office, or vehicle. The mount assembly may include a housing that encloses a cam and torsion spring disposed within a housing volume and has a portion that rotates relative to the cam. A recess in the mount assembly can receive and retain a mounting cleat associated with the first item. One or more clasp mechanisms of the mount assembly can be configured to clasp the mounting cleat when it is inserted into the recess, and to release the mounting cleat when the one housing portion is rotated relative to the cam. A locking mechanism may be included that prevents the housing from rotating and releasing the cleat.

Abstract: A protective case for use with a portable electronic device includes a protective shell and a cap. The protective shell is configured to at least partially encase the portable electronic device and includes an aperture configured to align with a receptacle of the portable electronic device when the portable electronic device is installed in the protective case. The aperture is configured to allow insertion of the stylus into the receptacle of the portable electronic device from outside the protective shell a cap removably insertable into the aperture of the protective shell to close the aperture. The cap is attachable to the stylus to facilitate removal of the stylus from the receptacle of the installed portable electronic device. The cap is configured to allow the stylus to extend into the receptacle to interact with the sensor of the portable electronic device while remaining attached to the stylus.

Abstract: A medical ventilator system that allows the use of pulse flow of oxygen to gain higher FIO2 values and/or conserve oxygen is described. In one embodiment, the ventilator system includes an oxygen concentrator, a medical ventilator and a breathing circuit between the ventilator and a patient. In one embodiment, the oxygen concentrator includes a controller module that is configured to generate a trigger signal to initiate the distribution of one or more pulses of oxygen from the oxygen concentrator to the patient circuit at the onset of a ventilator supplied breath. A small flow of oxygen can be added in between pulses to aid in gaining higher FIO2.
